WILLIAM McCREAVY, OF PHILADELPHIA, PENNSYLVANIA.

METAL-SHAPING APPARATUS.

To all whom 'it may concern:

Be it known that I, WILLIAM T. MCCREAVY,

a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Metal-Shaping Apparatus, of which the following is a specification.

My invention relates to improved metal shaping apparatus, the object of the invention being to provide improved means for shapin by means of rollers, rings and particular y rings ada ted for use 1n the connection with roller eax-ings.

Afurther object is to provide an improved apparatus of this character, which is deslgned particularly for utilizing the blanks -made -With my improved apparatus as set forth in my application Serial No. 526,165, 20 and rolling said blanks into rings of uniform diameter and thickness.

With these and other objects in view the invention consists of certain novel features of construction vand combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings,.1+`igure 1, is a view partly in sectlon andpartly in side elevation illustrating my improvements. Fig. 2, is a top plan v-iew partly in section. Fi 3, is a view of the blanks before rolling, and F 1g.v 4, is a view of the finished ring.

1 represents a bed plate or base having uprights 2, provided with fixed or integral.

inwardlyprojecting lateral projections 3 at theirupper ends, upon which circular top plate 4 is secured by bolts 5. The uprights 2 are made with alined bearings 6 on which Shafts 7 and 8 respectively are mounted. Fast and loose pulleys 9 and 10 are mounted on the shaft 8 to drive the apparatus and a balance wheel 11 is provided on the outer .end of shaft 7. These shafts 7 and 8 are provided with beveled ears 12 and 13 res ectiv'ely, both of whic mesh with a beve ed gear 14 on a vertical shaft 15. This vertical shaft 15 is made with a conical lower end 16 having a thrust bearing a 150 lgllzss cone 17 supported. in' a block 18 on e 1. The upper end of the shaft 15 is mounted to turn in anopening 19 in top 4,

'forward lower Patented oet. 25, 1910.

and is provided with a longitudinal opening or recess 20 as shown. The top 4 1s prov1ded centrally with a circular recess 21 .to 55 receive a ring 22, which latter serves as a Wearing ring and may be changed when worn,and is located directly above the ups. per end of shaft 15, which latter, it is understood, does not project entirely through the top 4.

23 represents a shaping journal pin, which 1s positioned in the recess 20 in shaft 15 and said shaft 15 and pin 23 are made with slots i 24 to accommodate a locking key 25 to se- 65 cure the journal pin 23 in the shaft and com pel it to turn with the shaft.-

26 represents a lateral extension at the top of the table preferably strengthened by web 27, and 28 is a similar extension at the 70. diametrically opposite side of the top which is also strengthened by web 29. On the extension 2G n tubular casing 30 is mounted and secured by bolts 31. This easing is preferably of rectangular form, internally, 75 in cross section, to permit longitudinal movement of the rectangular plunger. 32 on a bracket 33. This plunger 32 is provided with a reduced end 34 which moves through an opening 35 in the end of casin 30, and 80 a coiled sp1-inv 36is located in t e casing around tlus reduced end 34` and bears at one end against the end of casing-30, and at its other end against the rectangular portion, or enlarged porti0n, of the plunger3285 so as to normally press the plunger in adirection away from the casing.

lThe bracket 33 above referred to isl in the form of a late vhaving recesses in its face, in which shaping rollers 37 are located and mounted on journal pins 38 in the brackets. These rollers ,are disposed an equal distance from the shaping journal pin 23 andare adapted to I nove'y backward away from the pin during the 95 operation of the device as will more 4fully hereinafter appear. y i A lug39 is rovided on plun er 32 and A' a pivoted catcii 40 is Aconnecte with the lug 39 and is adapted, when the bracket 33"1Q 0 is moved backward, to fall behind the endc of casing 30 and hold the bracket .in this position against any forward movement. to ward pin 23,` until-the catch 40 is released,

and the casing 30 is made with a short slot or recess 41 to accommodate lug 39 and permit the desired movement thereof.

42 represents an internally screw threaded sleeve, which is secured by the bolts 43, and receives a screw 44. The inner end of this screw 44 is swiveled in a bracket 45, the latter having a recess in its end face to accommodate a shifting roll 46, which is mounted upon the journal pin 47. The outer end of the screw 44 is provided with a hand Wheel 48 to facilitate its turning to exert the desired pressure on the blank. These rolls 37 and 4G are rovided with annular flanges 49 around t eir upper edges, -so as to prevent the spreading of the blank. Fig. 3 represents the blanks as they come from the apparatus disclosed in my application above referred to and `these blanks whenA heated are placed over the pin 23, the latterprojecting through the hole 50 inthe blank. Roller46 is then moved up into close engagement with the blank 51 and the shaft 8 turned by means ofthe driving pulley to transmit motion through gears 13 and 14 to shaft 15, to turn pin 23, and as the latter turnsv the blank illustrated at 51 willibe turned between the pin 23 and roller 46, and will be shaped, so as to have a uniform annular thickness afterr one Aor more revolutions, it being understood that wheels 37 will move backward to accommodate an virregularities in the surface of blank 51.

As the apparatuscontinues to operate the workman will slowly turn hand wheel 48 So as to press the wheel 46 nearer pin 23, and as -he does this the thickness of the ring bein shaped will be gradually diminished, an at the same time, the diameter of the-ring' will be increased, and rollers 37 will move backward to accommodate this increased diameter of the ring. lVhen the catch 40 falls behind casing 30 the operation will vbe completed. The workman then simply unscrews the screw 44 and draws the wheel 46 back when he can readilyremove the finished rin As shown in Fig. 3 these blanks preferab7 come from my improved apparatus above referred to in the form ot a plurality of blanks having a fragile juneture, which renders it easy to handle the blanks which may be heated and placed over the in 23, when by a twisting movement, the lank maybe broken at its point of fragile c pnnection.- y

A great many slight changes might be made in 'the general form and'arrangement 1 of parts described without departing from my invention and hence l do not restrict myself toA the precise details set forth, but

consider myself at' liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

Haring thus described my invention what l claim as new and desire to secure by Letscribed, Athe combination with a supporting top or table, of a rotary shaft projecting above said top, two brackets mounted on said top at opposite sides of said pin, a. single roller'in one of said brackets,a screw for positively moving said bracket toward and away from said in, two rollers mounted in the other of said brackets, a spring normally pressing said last mentioned bracket toward Said pin, and a catch; on said `last mentioned bracket, adapted to hold the bracket against movement toward the pin.
